FEEDING MECHANISM FOR-TABULATING MACHINES.

Original application filed October 16, 1924, Serial No. 743,940.Divided'and this application filed May 11, p

This invention relates to automatic tabulating machines controlled byanalyzers or sensing mechanisms in turn operated by. perforations inrecord cards and relates more a particularly to a card feeding meanswhich while adapt-able for use with various klnds of card controlledmachines has more particular reference to anautomatic total talc ingmechanism as shown in'my copending application, Serial No. 743,940,filed October 16, 1924, and of which this application for patent is adivision.

Heretofore I have invented several machinesof the tablulating,accounting and other types embodying card feeding means,

and the present invention is an improvement over" such feeding means andany others of. which I am aware.

Some of the objects of the present invention are to provide a cardmagazine which cannot be loaded with the cards upside down or backwards;to provide a card magazine and picker mechanism capable of taking at oneloading a very large number of small groups of cardswithout'objectionable pressure on the picker such as would interfere 4with feeding; to provide a card feeding mechanism having suctionmeansfor properly positioning the card adjacent to the picker blade toeffect positive and reliable feed ing; to provide a picker mechanisminwhich the feeding may be prevented or disabled without the necessityof stopping the reciprocation of the picker, and to provide a magazinesupport over the picker which is supported to one side thereof to beswung out of the way to give convenient access to the picker forinspection or adjustment; to provide apparatus of this kind which isdurable, economical to manufacture, easy to operate, which will noteasily get out of order, and in general to improve the simplicity-"andefliciency of card control mechanisms; and to provide other improvementsas will hereinafter appear.

One form of the present invention for the accomplishment of these andother objects is shown herein in connection with a tabulating machinehaving a card analyzer pro- 00 vided with analyzing pins arranged topass 1925. Serial no. 29,470.

through perforations punched in control cards, and a magazine forholding groups of the'control cards which are fed by a picker mechanismfrom the magazine to the analyzer. The magazine embodies a. feature ofthe invention in that it is constructed to per mit the -feeding of onecard group while withholding the next successive group from feedinguntil there has been a. change in posit-ion of the magazine. The feedingof the cards and the group control feeding is automatically controlledby a feeler device which is caused to function as soona's it is relievedof the weight of acard'.

Certain parts of the mechanism such asthe picker, the pin box, and the clutch and shield throwing mechanismare shown in operated position in certain of the views for purposes ofdescription.

The analyzer comprises fixed upper and lower spaced perforated analyzeror registration plates 12 and 13 (Fig. 12), between which perforatedcards are fed and positioned, so that a vertically reciprocatory pm box14, carrying yieldable projected analyzer pins 15, can coact therewith.The pins 15 in the upper or operative position of the pin box passthrough the perforations 16 of the lower plate 13 to engage a card 17(Fig. 4), at points where no perforation exists in the card or to passthrough perforations in the card and into the registering perforations18 of the upper plate 12 where they respectively engageand raiseterminal pins 19, slidably card trol the, setting and registering ofnumbersmounted in a fixed member, of which a perforated plate 20 formsthe upper guide for the ins. Such pins 19 as are projected upwar lbyreason of the perforations in the fimc'tion in a well-known manner toconin the adding machine 10 by raising the pins 1 31. For the purpose offeeding cards to the registration plates pairs of feed rolls 22 are 26,projects a short distance through a .slot in a card supporting plate 32(Fig. 7), this latter being mounted fast on the picker block 26 andprovided with a rear .extension 33, (Fig. 5), and a pair of-forwardextensions 34 so arranged as to form an opening 35 to receive the throatblock 25 as the picker block moves forward. A card positioning guide Thecard magazine.

A magazine base 43 resting on said guide frame 38 is provided at one endwith a boss 44 pivotally received on a bearing bushing 45 carried in aprojection 46 of the frame 23. A bolt bracket 47 at the opposite end ofsaid base is provided with a Vertical bore 48 hav ing an enlarged lowerportion 49 defining a shoulder. provided at the upper end with amanipulating wheel52 and at the lower end with a collar 53 guiding thebolt in the bore at the lower end. Aspring 54 in said enlarged portioncompressed between the said shoulder and said collar presses thelowerrounded end ofthe bolt into an opening 55 to hold the card shapedopening 56 of said base in registration with the guide frame 38. Aretaining member 57 mounted on said frame is provided with an undercutgroove in which may be engaged an arcuate projection 58 on said collar53 to hold the bolt in locked position. When the bolt 50 is unlocked andraisedthe base 43 may be swung entirely clear of the guide frame 38,thus to vgive'unobstructed. access to the picker. A gear plate 60rotatably-disposed in anannulargroove 61 of the magazine base and onbearing ribs 62 on said located adj acent'to the inlet side of theregis-- base is provided with an intra marginal tration mechanism andproperly alined with trespect thereto, so thatthe cards fed throughthese rolls are delivered one after another into the registrationpassage in proper timed relation. The delivery of the cards to the rolls22 and the proper timing thereof takes place through the medium of a.feeding mechanism comprising a picker supporting frame 23 (Figs. 1, 2and-5) provided with guide channels 24 across the ends and a throatblock 25 at the discharge side or side toward the feed rolls'22, theguide channels -24 serving to slidably support an elongated picker block26 by means of end shoes 27. This picker block 26 is reciprocated bymeans of a picker lever 28 (Fig. 7) actuated from a cam 29 on the mainshaft 30, as described in the aforesaid patents. The picker blade 31,which-is seODFed on the rear of the block cross-shaped opening 63 (Figs.2 and 3).

The opposite ends of this opening are adapted'to register with said cardshaped opening 56 of the base when the gear plate is disposed at eitherof its two normal positions at right angles to each other. A. retainingring 64 fast on base 43 holds said gear plateau position and carries astop pin 65 adapted to be engaged by'stop plates 66 mounted fast on saidgear plate 60 to stop said plate in the registering positions. Card endguides 68 mounted on said gear plate are formed with end and side walls69 and 70 for engaging and positioning the cards 17 to hold them in thecrossed or staggered relation in which they are stacked, as shown of andguides is bevelled to engage the out.

A bolt 50 slidable in said bore is off corners 72 of the cards toprevent the misplacing of the cards in the end guides, so the cardscannot be fed backwards or upside down. i

The lower cards of the lowest group, or all of the lowest group, if thegroup be small, drop through the opening 56 into the guide frame 38,whereupon the lowest card rests on the supporting plate 32 to be'engaged by the picker blade and fed through the card gate to the. feedrollers and thence to the analyzer. The feeding action continues untilall of the cards are fed from the lowest group, the cards of the groupnext above in the meantime resting on the base 43 and the ribs 62thereof, which thus act as a preventing means to hold said group fromthe picker. When the last card is fed from the lowest group, certainautomatic actions, later to be described, are set up which causes thetaking of the total of said lowest group and the shifting of the gearplate 60 and everything carried thereon through 90 to bring said next tothe lowest group, which has now become the lowest group, intoregistration with the card shaped opening 56 and the guide frame 38,whereupon the feeding of cards is resumed. The gear plate 60 is slightlygrooved to receive the ribs 62 to prevent cards getting between the gearplate and base when the gear plate is shifted.

If the card groups are small and of less height than the guide frame 38,the next to thelowest group will always be supported by the base 43 andthus carry the load of all the cards above' and relieve the pressure onthe lowest group and the picker. This is i an important advantage of thepresent invention. With my former machine it was not possible to feedthe cards properly when a large number of cards was placed in themagazine as the weight of these cards exerted too great a pressure onthe picker, whereas with the present invention a hundred or more ofthese small groups can be placed in the magazine at once, while only theweight of the lowest group bears on the icker. This advantage permits aJsingleoperator to load one machine while other machines are working andthusattend several more machines than was possible with my formermachine.

The suction card positioner. I

In my earliest machine, some difiiculty was experienced in making thecards lie fiat on the picker and throat block for effecting positive andreliable feeding. To remedy this it has been customary to place a fiatweight upon the cards, but even this fails to give perfect results everytime, especially when 'only one or a few cards are in the magazine. Iovercome this difliculty by Suetion means which .will now be described.

throat block. A U-shaped pipe 81 extending to orifices 82 near thepicker blade and extending through the picker block and the supportingplate 32 is connected by a flexible tube to said suction pipe, wherebysuction from the pump acts to hold the cards firmly upon the plate 32and the throat block as the cards are fed, thereby in'suring'thepositive feeding of the cards.

This suction means is much more effective than the above mentionedweight and-is positive and reliable even with a single card in themagazine. I

The card feeler or sensing mechanism.

The above mentioned automatic actions arebrought about by the action ofa card feeler 85 (Figs, 2, 3, 5, 7, 10 and 11) supported in .a strapbracket 86 mounted on'the base 23 at the rear face of the picker blockto rovide a vertical guideway for the thin fee er shank 87 (Fig. 10)disposed in said guideway with its edges in the direction of the path ofthe cards and provided at the rear edge with a recess 88. Theupper endof the shank is provided with a flat head 89 for engagement with thebottommo'st card.

Aflat spring 90 (Fig. 3 mounted on the lower face of the pickersupporting frame 23 engages the lower end of said shank and is juststrong enough to raise the feeler when no card is resting thereon andweak enough to be depressed by the feeler when a'single card reststhereon.

. I Levers 93; (Fig. 5) disposedlongitudmallv of the picker block areintermediately fulcrumed, as at 94, on the lower face of said forwardextensions 34 for movement in a horizontalplane and have their innerends 95 disposed directly behind the shank 87 (Figs. 10 and 11), wherebywhen the feeler is depressed and said picker block is moved forward,said inner ends 95 will engage the said shank and will be oscillated,(Fig. 10), On the other hand, if said feeler is raised by said flatspring when no card is resting on the feeler, said inner ends 95 willengage in said recess 88 (Fig. 11). and said levers will not beoscillated.

When said levers are oscillated they project forwardly a pair of pushrods 97 (Figs. 5 and 10) having their rear ends pivoted to the outerends of said levers .93 and pro- .vided intermediately with longitudinalslots 98 receiving retaining pins 99 mounted on said'forward extensions34. for retaining and guiding the push rods forwardly.

A rock shaft 100 (Figs. 9, 12 and 1s dis-f posed transversely across themachine below the path of the cards and mounted in the' by means of anoscillating lever 101 having its upper end fast on said rock shaft andits lower end forwardly turned to form an elbow portion 103 (Figs. 12and 14) and bifurcated to provide a pair of lateral members 104 engagingon both sides of the main shaft 30 for guiding the lever. A roller 105mounted on the side face of said elbow part engages in a lateral camgroove 106 of a cam 107 mounted on said main shaft. major portion ofsaid groove is concentric with main shaft, a small portion 109 of. thegroovebeing inwardly curved to give a quick movement of the oscillatinglever 101 during that part of each cycle when the analyzer pins 15 arein their lowered positions The rock shaft 100, (Figs. 9 and 13), carriestwo sleeves 110 loosely mounted for independent movement relativethereto and having lever arms 111 fast thereon and respectively in thepath of movement of the push rods 97, (Figs. 8, 10 and 11), so that whenthe latter are actuated the arms 111 will be rocked clockwise againstthe action of the springs 112. The sleeves 110 are respectively providedwith lifting arms 113 fixed thereon, each of which has a laterallyturned flange 114 arranged in normal position of the arms 11-1 to engageand support adownwardly projecting cam face 115 at one end of a dog116.The dogs 116 are re spectively pivoted upon upwardly and forwardlyinclined arms 117, which are fast upon the rock shaft 100. Springs 118yieldably hold the dogs 116 in depressed .engage ment with therespective flanges 114. In

operation the rods 97. are normally projected each time the picker feedsa card forwardly, thus pushing the arms 111' for-, wardly and moving thearms 113 from beneath the dogs 116 which thereupon fall when moved tothe left so that the teeth 120 )Vhen the picker moves back, the rods 97and the arms 111 and 113 are returned to normal position by the retractin of the springs 112, and the dogs 116'a1'e againraised to bring a toothof each into its segment notch 121 as the dogs are moved to the left.Thus the dogs 116 are lowered once for each adding cycle of the machineand are held lowered at the time the cam groove 109 is at the positionof Figs. 12 and 14.

This timing relation is arranged so that the rocking movement of theshaft 100 is transmitted through the dogs 116 to the segments 122, whenthe dogs are held raised as in the The absence of a card, to rock anupper shaft 123 mounted'in the frame'23, by which certain functions ofthe machine are carried 7 out.

The magazine shift.

this card shift and move it ii timed rela tion with the other adjunctsof the machine, a total initiating shaft 124 is provided and mountedacross the lower part of the ma- I In accordance with the presentinvention,

chine in bearing brackets 125 and 126 (Fig.

9), and this shaft 124, as fully explained in my original application,serves to cause the total taking mechanism to function. Motion isperiodically transmitted to the initiating shaft 124 by the provision'of a sleeve 127 (Figs. 16 and 17), rotatably mounted on the shaft 124and receiving motion by means of reduction gears 128 and 130 interposedbetween the sleeve 127 and the main shaft30, the-arrangement being suchthat the sleeve is rotated in the present instance at half the speed ofthe aforesaid main shaft. A disc 131 fast on the sleeve 127 is providedwith.

diametrically opposite lugs 132, which are arranged to be engaged by ashiftable clutch bolt 133 provided with a head 134 which is normallyengaged by a cam lever 135. The clutch bolt 133 is splined in ahorizontal bore 136 of a crank body 137' fast to -the shaft 124. The camlever 135 is slightly forwardly inclined away from the crank, as shownin Fig. 16, and is pivoted at its rear end to a bearing bracket 138 onbracket 126,

while its movable end is connected to a pend ent link 140, (Fig. 15),the upper end of which connects to a laterally projecting arm 141. Thisarm 141 is'fast to a shaft 142 mounted for rocking movement in abracket' per shaft 123. The lever 144 is provided with a transverseclearance opening 147 through which passes the rock shaft 100, thoughthe parts are out of contact, to permit the proper relative movement, aswill be understood. I

For transmitting motioirfrom the initiating shaft "124 to the magazineshifting mechanism, a gear 150, (Figs. 16 and 17), fixed to the shaft124 is in mesh-with a gear 151 fast on a cam shaft 152 journalled in. abracket 153 and provided with a cam 154 having a side face cam groove155, the ratio of the gearing being such that the cam 154 isrotatedone-half of a rotation for'each complete rotation of the shaft124. A roller 156 is arranged to travel in' the groove 155 and ismounted upon pin 157 attached to a shift link158 having a slot 160 atone end vertically disposed stud shaft 165, to the lower end portion ofwhich is keyed a gear 166 1n mesh with a smaller gear 167 which is keyedto the lower end of a spindle 168 in order to transmit motion to acollar 170,

(Fig. 2), on its upper end. The spindle 168 is journalled at its lowerend in'an extension 171, (Fig. 17), of a bracket 172, while its upperend is journalled in the bearing bushing 45, (Fig. 3), of the pickerframe 23. The collar 170 is provided with a radially disposed lug 173,(Figs. 2 and 3), which extends parallel and in close proximity to theface of a drive pinion 174 and is arranged to transmit motion to thelatter by engagement with the free ends of pawl-like members 175respectively pivoted on the upper face of the drive pinion and heldtogether abutting opposite sides of the lug 17 3 by means of a spring176. In this way the two members 175 are yieldably held pressing againstthe lug 173 while interposed pins 177 limit the inward movement of thesemembers so that a yielding action is made possible between the spindle168 and the drive pinion 174 to prevent the breaking of any of the gearsshould the magazine he accidentally held stationary. It will thus beseen that each time the shaft 124 isrotated the cam 154moves 180 and thebar 158 .moves from one limit-to the other and rotates the pinion 164,the gears 166 and 167 to transmit motion to the spindle 168 and byvmeans of the yielding connection rotate the pinion 17 4 so that the gearplate GO'is'turned The teeth and diameters of the pinions, gears andgear plates .are such that one complete movement of the link 158 gives aquarter rotation to the gear plate and the parts carried thereon.

The operation.

printed cards or lmperforated cards of any p kind are grouped as forcounting, the

grouping will take place as the various cards .ing a total are-selecteddepending upon the manner of selection under the given circumstances.

The cards having been grouped or stacked as shown in Fig. 4, a suitablenumber of groups are placed in the magazine, the bevelled corners 71(Fig. 2) insuring that they are properly directed. The lowest groupshould preferably register 'with the. card shaped opening 56. The heightof the end guides 68 and the card guide 38 need notbe limited to theheights illustrated; and if the'ca'rd groups are small, a large numberof them may be placed in" the magazine at once as hereinbefore fullyexplained.

Preferably the machine is started after the cards are in the magazine,since if not, the machine will go through the action of taking andclearing zero totals, that is, takthe machine. If the lowest group isnot in the card guide frame 38, the machine will take a zero tot'aFandshift the magazine 90 and drop the lowest group into the guide frame 38.

With the magazine loaded and with cards 38 and the machine in the guideframe started, the suction at the orifices 80 and 82 positions th lowestcardtothe picker blade and on the throat block, depressing the that whenthe picker blade moves feeler 85, so

feed the card to the feed rolls forward to 22,

causing said levers to project forward the push rods 97 and push forwardthe arms 1 11 and 113 to permit the dogs 116 to drop down. The dogs'116are in their lowered position at the time that the camgroove portion 109and lever .101 are in the position shown in Fi do with'no numberregistered in the. recess 88 (Fig. 10) will be out of register with theends of the levers 93 total is not taken, nor is the position of the 7magazine changed. From the feed rolls, the cards pass between theanalyzer plates 12 and 13, and the cards are analyzed in the ordinaryway and pass on to the usual card receptacle (not shown).

The above ation continues until all of the cards of a group have beenfed from the magazine. -When the cards of any group are ex- I analyzingor registering operhausted, the cards of the group next above.

are still resting crosswise of the card shaped opening 56 (Fig. 3) andon the base 43 (Fig.

2) so that no more cards can reach the picker until the magazineisrotated a quarter turn,

as previously explained. \Vhen it thus hapens that the last card is fedfrom the picker and no card rests on the feeler, the feeler will rise(Fig. 11) under the action of the spring 90 (Fig. 3), the ends 95 of thelevers 93 (Fig. 11) will be received in the recess 88, the push rods 97(Fig. 2) will not be ushed forward as the picker moves forwar arms 111and 113, (Fig. 13), will not move forward and the dogs 116 will not bedropped down when the cam groove portion 109 reaches the position ofFig. 14.

When the cam groove portion 109 passes position of. Fig. 14, it rocksthe lever 101 and arm 117 in a direction clockwise as shown in Figs. 12and 14, whereby the dogs 116 move the-notched arms 122, (Fig. 15,),rocking the upper shaft 123 and sector 146 in a counter-clockwisedirection, thus rocking the lever 144 and associated parts causing thedepression of the cam lever 135 and the release of the bolt 133 (Figs.15 and 16) to move into engagement with one of the constantly revolvinglugs 132, whereby the total initiating shaft"124 is given one completerotation, bringing the bolt head 134 again into camming engagement withthe cam lever 135 (see Fig. 16) and causing the withdrawal of the boltfrom the lug 132 to permit the shaft 124 to come to rest. As the sleeve127 rotates with half the speed of the main shaft, it is necessary tohave two lugs 132 in order that a lug be presented to the bolt 133 onceduring every cycle'of the machine. i

' This single rotation of the initiating shaft 124 is so arranged, asexplained in the original application, that during the first half ofrotation there will be no actuation of the. total taking mechanism,because it isneces- 'sary for the main shaft and the pm boxwhich maketwo cycles during the rotation of the initiating shaft to complete an1d1e cycle while the analyzer pins are being held down. This gives timefor the completion of the adding operation and at the proper time in thecycle the total taking'shaft is caused to function in the requiredmanner. This single rotation of the initiating shaft 124 also bringsabout a half rotation of the shift cam 154, and the consequent shiftingof the bar 158 from one limit to the other.

The movement of the shift bar 158 is transmitted by way of the rack 163and gearing 164, 166 and 167 "to the spindle 168 and there transmittedthrough gear 174 to the magazine supporting gear plate to cause thelatter to rotate through to bring the card group which was restingon thebase 43 in registration with the card shaped open- .ing 56 to permitthis group, which has now become the lowest group, to take a positionresting upon the picker and depress the 'feeler 85 so thatfurtherrocking of the upper shaft 123 is prevented until the analyzingand adding of the group is complete, as heretofore described. The aboveoperations are repeated as long as cards are suppliedto the magazine.

While only a single form in shown in which this invention may beembodied, it is magazine, and means associated with said magazine fordelaying co-operation of said feeding means with'the group nextsucceeding the group being fed, whereby an interruption of feedingautomatically takes place between groups. p
